| sub526 | Hi all, I’m having two identical Linux x86_64 systems with different Ubuntu kernel versions. The 1st one has Ubuntu 16.04.4 LTS kernel and the 2nd systems has Ubuntu 18.04.4 LTSkernel. I see that, the older distro version kernel(Ubuntu 16.04.4 LTS) is bit faster compared to the system with later version(Ubuntu 18.04.4 LTS). perf bench sched | 06:58 |
|---|---|---|
| sub526 | messaging -g 64 resulted "Total time: 2.838 [sec]" in older Ubuntu version whereas in other machine "Total time: 9.834 [sec]". Also, time taken to load the driver(insmod) also varies between two systems. What is best way to debug and solve this issue? | 06:58 |
| sub526 | Ubuntu 16.04 machine has 4.4.0-66-generic kernel and Ubuntu 18.04 machine has 4.15.0-91-generic | 07:20 |
